RKZ Closing Sequence Regulator for Arm Door Closers 280x90 mm Stainless Steel Double-Leaf

Product Overview

The closing sequence regulator RKZ (280x90 mm) is installed on double-leaf doors equipped with arm-type door closers, primarily in commercial and institutional settings where controlled closing order and secure access are required. Manufactured from stainless steel, this device ensures the proper closure of active and passive leaves, preventing misalignment or unfinished closing in high-traffic environments.

Unlike general closing solutions, the RKZ is specifically designed to hold the active door leaf until the passive leaf completes its closing cycle. This reduces malfunctions and eliminates the risk of both leaves remaining partially open, a critical concern for fire and security doors. Facilities managers and contractors working with fire-rated or security double doors will find it especially suitable for compliant installations and retrofit projects.
